The graph shown compares the number of pages of the same book read by Emily and Serena over time.

iragen [17]

Using linear equations, the number of minutes that both would read for them to read equal number of pages is: 30 minutes.

<h3>What is the Equation of a Linear Graph?</h3>

Equation of a linear graph is given as, y = mx + b, where m and b are the slope and y-intercept of the graph respectively.

Equation for Emily's graph:

Slope (m) = rise/run = 1/3

y-intercept (b) = 2

Substitute m = 1/3 and b = 2 into y = mx + b

y = 1/3x + 2

Equation for Serena's graph:

Slope (m) = rise/run = 2/5

y-intercept (b) = 0

Substitute m = 2/5 and b = 0 into y = mx + b

y = 2/5x + 0

y = 2/5x

To find how many minutes for both of them to read the same number of pages, make both equations equal to each other.

2/5x = 1/3x + 2

2/5x - 1/3x = 2

1/15x = 2

Multiply both sides by 15

x = (2)(15)

x = 30

The answer is 30 minutes for both to read the same number of pages.

A cuboid has a square base.

padilas [110]

The length of one side of the square base is 8.5 centimeters.

<u>Given the following data:</u>

Volume of cuboid = 867 cm

Height = 12 cm

To find the length of one side of the square base:

Mathematically, the volume of a cuboid is given by the formula:

$Volume = Base \; area$ × $Height$

Substituting the given values, we have:

$867 = Base \; area$ × $12$

$Base\;area = \frac{867}{12}$

Base area = 72.225 $cm^2$

Now, we can find the length by using the formula:

$Area \;of\;a \;square = length^2$

$72.25 = length^2$

$Length = \sqrt{72.25}$

<em>Length</em><em> = </em><em>8.5 centimeters</em>.

Therefore, the length of one side of the square base is 8.5 centimeters.

A supermarket had bags of blue grapes for $18.00 for 4 bags. They also had bags of green grapes priced at $6.04 for 2 bags. Whic

Oduvanchick [21]

Answer:

Blue grape in most expensive

Step-by-step explanation:

Given:

Amount of blue grapes = $18

Number of blue grapes = 4 bags

Amount of green grapes = $6.04

Number of green grapes = 2 bags

Find:

Which grape in most expensive

Computation:

Cost of blue grapes = 18 / 4

Cost of blue grapes = $4.5

Cost of green grapes = 6.04 / 2

Cost of green grapes = $3.02

Blue grape in most expensive

Please help!!! i'm having some trouble with this question

QveST [7]

STEP 1
Bandages: multiply number of total kits by number of bandages per kit

9 * 24= 216 bandages total

STEP 2
Antiseptic Wipes: multiply number of total kits by number of antiseptic wipes per kit

9 * 16= 144 antiseptic wipes total

STEP 3
find difference between steps 1 & 2
= 216 bandages - 144 antiseptic wipes
= 72 more bandages

ANSWER: She packed 72 more bandages than antiseptic wipes.

Hope this helps! :)
